Sony has a business partnership with the esteemed German lens design
company Carl Zeiss, and many of Sony's cameras bear this distinguished
brand name. It is notable by its absence from the lens on the H1, but I
wouldn't be surprised to learn that Carl Zeiss had a hand in its design,
because it's quite a piece of work. It can focus down to 2cm, it has a
maximum aperture of F2.8-3.7, which is remarkably fast for such a big
zoom, and as we'll see later it has amazingly good optical performance,
far better than most of its competitors.
